Method and apparatus for reproducing digital video signals |
摘要 |
A method and an apparatus for reproducing digital video signals in which every one-frame data of the digital video signals are recorded on n tracks of a recording medium by an inclined azimuth recording system are varying speed reproduced by a rotary head having n heads with a varying playback speed such that A=a(txm+/-1)/n, where a is a constant equal to 1 or 2 and m is a constant which is an integer other than 0. A picture corresponding to the digital video signals read out with the varying playback speed S is displayed on the screen. In this manner, non-continuous lines caused by temporal difference in neighboring macro-blocks during varying speed reproduction may be rendered less obtrusive for improving the picture quality of the varying speed reproduced picture.
